Boston ocular surface prosthesis: An Indian experience
Varsha Madanlal Rathi, Preeji Sudharman Mandathara, Srikanth Dumpati, Pravin K Vaddavalli, Virender S Sangwan
July-August 2011, 59(4):279-281
DOI:10.4103/0301-4738.81994  PMID:21666311
Context: Boston ocular surface prosthesis (BOSP) is a scleral contact lens used in the management of patients who are rigid gas permeable (RGP) failures as with corneal ectasias such as keratoconus and in those patients who have ocular surface disease such as Stevens-Johnson syndrome (SJS). Aim: To report utilization of BOSP in a tertiary eye care center in India. Materials and Methods: We retrospectively reviewed charts of 32 patients who received BOSP from July 2008 to May 2009. Indications for fitting these lenses, improvement in visual acuity (VA) before and after lens fitting and relief of symptoms of pain and photophobia were noted. Paired t-test was used for statistical analysis using SPSS version 16.0 for Windows. Results: Thirty-two patients (43 eyes) received these lenses. These consisted of 23 eyes of 17 patients who failed RGP trials for irregular astigmatism and corneal ectasia such as keratoconus and post radial keratotomy and scar and 20 eyes of 15 patients with SJS. Mean age of RGP failures was 27.94 years. Pre- and post-BOSP wear mean LogMAR VA was 1.13 and 0.29, respectively, in RGP failures. The P value was statistically significant (P < 0.001). In patients with SJS, LogMAR VA was 0.84 ± 0.92 before and 0.56 ± 0.89 after lens wear. The P value was statistically significant (P < 0.001). VA improved by >2 lines in 7/20 eyes (35%) with SJS, with improvement in symptoms. Conclusion: BOSP improves VA in patients who have irregular astigmatism as in ectasias and RGP failures and improves vision and symptoms in patients with SJS.

Comparative study on the incidence and outcomes of pigmented versus non pigmented keratomycosis
Sabyasachi Sengupta, Sanjeevani Rajan, Padmati Ravindranath Reddy, Krishnan Thiruvengadakrishnan, Ravilla D Ravindran, Prajna Lalitha, C Manivasagam Vaitilingam
July-August 2011, 59(4):291-296
DOI:10.4103/0301-4738.81997  PMID:21666314
Purpose: To determine the incidence, outcomes and establish factors determining visual prognosis of keratomycosis due to pigmented fungi in comparison with nonpigmented fungi. Materials and Methods: All culture-proven cases of fungal keratitis from January 2006 to August 2008 were drawn from a computerized database and cases with adequate documentation were analyzed for predisposing factors, clinical characteristics, microbiology and treatment methods. Outcomes of keratitis due to pigmented and nonpigmented fungi were compared using t-test and χ2 test. Results: Of 373 cases of keratomycosis during the study period, pigmented fungi were etiological agents in 117 eyes (31.3%) and nonpigmented fungi in 256 eyes (68.7%). Eyes with nonpigmented keratitis had significantly larger ulcers (14.96 mm 2 ) and poorer vision (1.42 logMAR) at presentation compared to those with keratomycosis due to pigmented fungi (P=0.01). The characteristic macroscopic pigmentation was seen in only 14.5% in the pigmented keratitis group. Both groups responded favorably to medical therapy (78.1% vs. 69.1%) with scar formation (P=0.32) and showed a significant improvement in mean visual acuity compared with that at presentation (P<0.01). Visual improvement in terms of line gainers and losers in the subgroup of eyes that experienced healing was also similar. Location of the ulcer was the only factor that had significant predictive value for visual outcome (P=0.021). Conclusion: Incidence of keratomycosis due to pigmented fungi may be increasing as compared to previous data. These eyes have similar response to medical therapy and similar visual outcome compared to nonpigmented keratitis. Central ulcers have a poor visual outcome.

Dengue hemorrhagic fever: A rare cause of pituitary tumor hemorrhage and reversible vision loss
Vimal Kumar, Rashim Kataria, VS Mehta
July-August 2011, 59(4):311-312
DOI:10.4103/0301-4738.82002  PMID:21666319
Dengue hemorrhagic fever leading to hemorrhage in pituitary adenoma is not reported till date: We herein report the first case of bilateral visual loss secondary to pituitary adenoma hemorrhage associated with dengue hemorrhagic fever. Urgent transnasal trans sphenoidal decompression of the macroadenoma prevented permanent visual loss in this patient. Pituitary apoplexy should be considered as differential diagnosis of visual deterioration apart from retinal hemorrhage, maculopathy, and optic neuropathy in cases of dengue hemorrhagic fever. Early decompression of optic nerves helped in the restoration of vision.

Kumar Saurabh, Radha R Das, Jyotirmay Biswas, Amitabh Kumar
July-August 2011, 59(4):297-301
DOI:10.4103/0301-4738.81998  PMID:21666315
Aims: To provide a fact file on the etiology, clinical presentations and management of retinal vasculitis in Eastern India. Materials and Methods: Retrospective, record based analysis of retinal vasculitis cases in a tertiary care center in Eastern India from January 2007 to December 2009 . Results: One hundred and thirteen eyes of 70 patients of retinal vasculitis were included in this study. Sixty (85.7%) patients were male (mean age 33± 11.1 years) and 10 (14.3%) were female (mean age 32.4 ± 13.6 years). Vasculitis was bilateral in 43 (61.4%) and unilateral in 27 (38.6%) patients. Commonest symptoms were dimness of vision (73; 64.6%) and floaters (36; 31.9%). Vascular sheathing (82; 72.6%) and vitritis (51; 45.1%) were commonest signs. Mantoux test was positive in 21 (30%) patients but tuberculosis was confirmed in only four (5.71%) patients. Raised serum angiotensin-converting enzyme level and positive antinuclear antibody level were reported in four (5.71%) patients each. Human leukocyte antigen B5 (HLA B5) marker was present in one (1.4%) patient. However, none of the total 70 patients were found to have a conclusively proven systemic disease attributable as the cause of retinal vasculitis. Oral corticosteroid (60; 85.7%) was the mainstay of treatment. Forty-eight (42.5%) eyes maintained their initial visual acuity and 43 (38%) gained one or more line at mean follow-up of 16.6± 6.3 months. Conclusion: Retinal vasculitis cases had similar clinical presentations and common treatment plan. There was no systemic disease association with vasculitis warranting a careful approach in prescribing investigations.

Extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue type of the ocular adnexa: Retrospective single institution review of 95 patients
Su-Ho Lim, Minkyu Kang, Junhyuk Son
July-August 2011, 59(4):273-277
DOI:10.4103/0301-4738.81993  PMID:21666310
Context: There are few reports on the management of extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue type (MALT), which are based on the experience of a single institution, as opposed to large multicenter randomized trials. Aim: The aim of this study was to report on the clinical experience of a single institution. Materials and Methods: A retrospective review was undertaken of records of 95 patients with MALT lymphoma of the ocular adnexa. Histologic diagnosis of MALT lymphoma was made according to established criteria, and clinical staging was carried out to determine treatment modalities. All patients were treated by external beam irradiation (30.6-45.0 Gy) after biopsy. Additional chemotherapy was performed in accordance with the clinical stage of the disease. All the patients were treated by the same hemato-oncologist and radio-oncologist. Results: Almost all patients showed complete response, except for four patients who showed partial response. In two of 95 patients, contralateral eye showed recurrence, and they were salvaged by additional radiotherapy. The 3-year overall survival and event-free survival rates were 100 and 97%, respectively, by Kaplan-Meier survival analysis. Moreover, there were no serious radiation-associated complications. Conclusions: Radiotherapy alone can be an important treatment modality for the local control and survival in patients with localized MALT lymphoma of ocular adnexa. Systemic chemotherapy should be considered in patients with advanced stage disease.

Rajul S Parikh, Shefali R Parikh, B Debashish, BL Harsha, Ravi Thomas
July-August 2011, 59(4):312-314
DOI:10.4103/0301-4738.82003  PMID:21666320
We report an unusual presentation of a case of Axenfeld-Rieger (A-R) syndrome. A 14-year-old male presented with gradual dimness of vision for 1 year and redness of left eye for 3 days. The patient had megalocornea with Haab's striae in the right eye and posterior embryotoxon in both the eyes. In the left eye, there was a white cord-like structure traversing the anterior chamber with adhesions to iris tissue along its course. On two antiglaucoma medications, his intraocular pressure (IOP) was 22 mm Hg in the right eye and 18 mm Hg in the left eye. Gonioscopy revealed a cord-like structure originating at the level of Schwalbe's line. He underwent right eye trabeculectomy with mitomycin-C. This case highlights a rare presentation of a strange cord-like structure, a rare presentation of A-R syndrome.

Rajesh Sinha, Namrata Sharma, Rakesh Ahuja, Chandrashekhar Kumar, Rasik B Vajpayee
July-August 2011, 59(4):283-286
DOI:10.4103/0301-4738.81995  PMID:21666312
Aim: To evaluate the safety and efficacy of laser in-situ keratomileusis (LASIK) in eyes with residual/induced refractive error following radial keratotomy (RK). Design: Retrospective study. Materials and Methods: A retrospective analysis of data of 18 eyes of 10 patients, who had undergone LASIK for refractive error following RK, was performed. All the patients had undergone RK in both eyes at least one year before LASIK. Parameters like uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), contrast sensitivity, glare acuity and corneal parameters were evaluated both preoperatively and postoperatively. Statistical Software: STATA-9.0. Results: The mean UCVA before LASIK was 0.16±0.16 which improved to 0.64 ± 0.22 ( P < 0.001) after one year following LASIK. Fourteen eyes (out of 18) had UCVA of ≥ 20/30 on Snellen's acuity chart at one year following LASIK. The mean BCVA before LASIK was 0.75 ± 0.18. This improved to 0.87 ± 0.16 at one year following LASIK. The mean spherical refractive error at the time of LASIK and at one year after the procedure was -5.37 ± 4.83 diopters (D) and -0.22 ± 1.45D, respectively. Only three eyes had a residual spherical refractive error of ≥ 1.0D at one year follow-up. In two eyes, we noted opening up of the RK incisions. No eye developed epithelial in-growth till 1 year after LASIK. Conclusion: LASIK is effective in treating refractive error following RK. However, it carries the risk of flap-related complications like opening up of the previously placed RK incisions and splitting of the corneal flap.

Influence of galactose cataract on erythrocytic and lenticular glutathione metabolism in albino rats
M Jyothi, R Sanil, S Shashidhar
July-August 2011, 59(4):287-290
DOI:10.4103/0301-4738.81996  PMID:21666313
Context: Glutathione depletion has been postulated to be the prime reason for galactose cataract. The current research seeks the prospect of targeting erythrocytes to pursue the lens metabolism by studying the glutathione system. Aims: To study the activity of the glutathione-linked scavenger enzyme system in the erythrocyte and lens of rats with cataract. Materials and Methods: Experiments were conducted in 36 male albino rats weighing 80 ± 20 g of 28 days of age. The rats were divided into two major groups, viz. experimental and control. Six rats in each group were sacrificed every 10 days, for 30 days. Cataract was induced in the experimental group by feeding the rats 30% galactose (w/w). The involvement of reduced glutathione (GSH) and the linked enzymes was studied in the erythrocytes and lens of cataractous as well as control rats. Statistical Analysis: Parametric tests like one-way ANOVA and Student's 't' test were used for comparison. Correlation linear plot was used to compare the erythrocyte and lens metabolism. Results: Theconcentration of GSH and the activity of linked enzymes were found decreased with the progression of cataract, and also in comparison to the control. The same linear fashion was also observed in the erythrocytes. Conclusion: Depletion of GSH was the prime factor for initiating galactose cataract in the rat model. This depletion may in turn result in enzyme inactivation leading to cross-linking of protein and glycation. The correlation analysis specifies that the biochemical mechanism in the erythrocytes and lens is similar in the rat model.

Role of anterior segment optical coherence tomogram in Descemet's membrane detachment
Sonia Kothari, Kulin Kothari, Rajul S Parikh
July-August 2011, 59(4):303-305
DOI:10.4103/0301-4738.81999  PMID:21666316
Descemet's membrane detachment (DD) is a rare but serious complication of intraocular surgery. In rare cases where corneal edema is severe and we may not be able to visualize DD on slit-lamp examination, anterior segment optical coherence tomogram (AS-OCT) would be helpful. We describe two patients with DD, highlighting the role of AS-OCT in early diagnosis and management of patients with DD. One of the patients had DD with rolled in edge, which could only be visualized with AS-OCT. In such a situation, AS-OCT can identify the edge of detachment and show the exact position of the rolled edge, which can allow us to plan the surgical strategy to unroll the DD.

Angioid streaks also called Knapp striae are small breaks in the Bruch's membrane and have been reported with a host of systemic diseases. Rupture of streaks or development of secondary choroidal neovascular membrane (CNVM) carries a dismal visual prognosis. We report the successful treatment of CNVM secondary to Paget's disease using low fluence photodynamic therapy (PDT) and intravitreal ranibizumab.

Can we overcome the challenges of sutures in lamellar keratoplasty?
Anita Panda, Sandeep Kumar
July-August 2011, 59(4):308-310
DOI:10.4103/0301-4738.82001  PMID:21666318
Lamellar keratoplasty (LK) is a technique which can be followed for both tectonic and optical purposes. We describe a technique of sutureless anterior LK by fixing the donor lenticule to the recipient bed using fibrin glue. LK was performed in an eye with corneal opacity using the manual dissection method. The donor lenticule was cut with a microkeratome after fixing the corneoscleral rim in an artificial anterior chamber. The size of the donor lenticule was 8.5 mm and fixed to the recipient bed with fibrin glue. The surgical time was reduced significantly with this technique. There was an uneventful postoperative period during the follow-up of 12 months. Best corrected visual acuity improved from hand movement to 20/60. Thus, the use of fibrin glue for fixing the anterior lamellar lenticule is a viable option for both optical and anatomical purposes.

Simultaneous bilensectomy and endothelial keratoplasty for angle-supported phakic intraocular lens-induced corneal decompensation
Vikas Mittal, Ruchi Mittal, Daljit Singh
July-August 2011, 59(4):314-317
DOI:10.4103/0301-4738.82004  PMID:21666321
A 40-year-old lady presented with severe endothelial cell loss in both eyes 14 years after angle-supported phakic intraocular lens (AS PIOL) implantation. The left eye had severe corneal edema with bullous keratopathy. The right eye had markedly reduced endothelial cell count (655 cells/mm 2 ) although the cornea was clear. She underwent simultaneous bilensectomy (AS PIOL explantation and phacoemulsification) and Descemet's stripping and endothelial keratoplasty (DSEK) in the left eye. Explanted AS PIOL was identified as ZSAL-4 (Morcher, Stuttgart, Germany) model. Corneal edema cleared completely in 2 months with a best corrected visual acuity (-2.25 D sph) of 20/60. No intervention was done in the right eye. The present case illustrates that AS PIOL-induced endothelial decompensation can be effectively managed by simultaneous bilensectomy and endothelial keratoplasty.

We report the case of a 16-year-old woman with microspherophakia and secondary open angle glaucoma. The patient presented with a membrane dividing the anterior chamber into two segments without edema or Descemet's membrane detachment. Slit lamp biomicroscopy, Pentacam, and specular microscopy images were obtained. Double anterior chamber is primarily found in patients with anterior chamber anomalies when there is no history of surgery or trauma.
