Iris claw intraocular lens: A viable option in monocular surgical aphakia
Raghavendra Rao, Ajita Sasidharan
February 2013, 61(2):74-75
DOI:10.4103/0301-4738.107198  PMID:23412525
To evaluate the safety and efficacy of iris claw intraocular lens (IOL) implantation for correction of monocular surgical aphakia in eyes with no capsular support. This is a prospective interventional case series of 30 eyes of monocular surgical aphakia. Patients underwent posterior iris claw implantation 4 weeks after the primary surgery. Aphakia which resulted due to posterior capsular rupture, large zonulo-dialysis (>180°) and cases of intracapsular cataract extraction in subluxated cataractous lens (>180°) where a posterior chamber IOL could not be placed were included in this study. Postoperatively, best-corrected visual acuity (BCVA) improved significantly (P < 0.02), 80% of patients had good vision of (20/20 to 20/40) and endothelial cell loss was 8.96% at 6 months. Secondary iris claw intraocular lens implantation is a viable option to correct monocular aphakia in eyes without capsular support.

Rohit C Khanna, Allen Foster, Sannapaneni Krishnaiah, Manohar K Mehta, Parikshit M Gogate
February 2013, 61(2):65-70
DOI:10.4103/0301-4738.107194  PMID:23412523
Context: Bilateral pediatric cataracts are important cause of visual impairment in children. Aim: To study the outcome of bilateral pediatric cataract surgery in young children. Setting and Design: Retrospective case series in a tertiary center. Materials and Methods: Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. Statistical Methods: Independent sample t-test, Fisher's exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA) version 12. Results: 215/257 (83.7%) patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months). Congenital cataract was present in 107 patients (58.2%) and developmental cataract in 77 patients (41.8%). The mean age at surgery was 55.2 months (range: 1-168 months). Out of 430 eyes, 269 (62.6%) had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months). Pre-operatively, 102 patients (47.3%) had visual acuity <6/60, in the better eye, compared to 37 patients (17.2%) post-operatively ( P < 0.001). Eighty-five patients (39.5%) had visual acuity >6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3%) and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%). The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5) and total cataract (OR: 4.8; 95% CI, 1.3-17). Conclusion: Nearly half of the eyes had visual acuity >6/18. The outcome was poorer in congenital cataracts, especially those operated after >1 year of age.

Multifocal and pattern-reversal visual evoked potentials vs. automated perimetry frequency-doubling technology matrix in optic neuritis
Marcella Nebbioso, Robert D Steigerwalt, JosŤ Pecori-Giraldi, Enzo M Vingolo
February 2013, 61(2):59-64
DOI:10.4103/0301-4738.99638  PMID:23412522
Background: To compare the usefulness of the traditional pattern-reversal Visual Evoked Potentials (VEP) with multifocal VEP (mfVEP) and Frequency-Doubling Technology (FDT) perimetry in the evaluation of the ocular abnormalities induced by acute or subacute optic neuritis (ON). Materials and Methods: The test results of 24 ON patients were compared with those obtained in 40 normal control subjects. MfVEP recordings were obtained by using an Optoelectronic Stimulator that extracts topographic VEP using a pseudorandom m-sequence stimulus. Receiver operator characteristic (ROC) curves were calculated to determine the sensitivity and specificity of abnormal values. Results: The frequency of the abnormal ocular findings differed in the ON patients according to the used technique. Reduced visual sensitivity was demonstrated in 12 eyes (54.5%) using FDT perimetry; 17 eyes (77.2%) showed decreased amplitude and/or an increase in the implicit time of the P1 wave in mfVEP and 20 eyes (90.9%) showed an abnormal decrease in the amplitude and/or an increase in the latency of the P100 peak at VEP examination. The areas under the ROC curves ranged from 0.743 to 0.935, with VEP having the largest areas. The VEP and mfVEP amplitudes and latencies yielded the greatest sensitivity and specificity. Conclusions: The mfVEP and the FDT perimetry can be used for the evaluation and monitoring of visual impairment in patients with ON. The most sensitive and practical diagnostic tool in patients with ON is, however, the traditional VEP. The mfVEP can be utilized in those cases with doubtful or negative VEP results.

Spontaneous expulsive suprachoroidal hemorrhage caused by decompensated liver disease
Krishnagopal Srikanth, M Ashok Kumar
February 2013, 61(2):78-79
DOI:10.4103/0301-4738.107201  PMID:23412527
Expulsive suprachoroidal hemorrhage can be surgical or spontaneous. Spontaneous expulsive suprachoroidal hemorrhage (SESCH) is a rare entity. Most of the reported cases of SESCH were caused by a combination of corneal pathology and glaucoma. We are reporting a rare presentation of SESCH with no pre-existing glaucoma or corneal pathology and caused by massive intra- and peri-ocular hemorrhage due to decompensated liver disease.

The British Asian Community Eye Study: Outline of results on the prevalence of eye disease in British Asians with origins from the Indian subcontinent
Abdul Rauf, Rizwan Malik, Catey Bunce, Richard Wormald
February 2013, 61(2):53-58
DOI:10.4103/0301-4738.107191  PMID:23412521
Background: Asians from the Indian Subcontinent form the largest ethnic minority in the United Kingdom. Data on the prevalence of visually-impairing eye conditions in this population are vital for planning eye health care services. Materials and Methods: This survey was based in the two London boroughs with the largest Asian populations. Subjects originating from the Indian Subcontinent were identified from GP practice records. All subjects were asked about demographic details and were given a full ophthalmological examination. The severity of cataract, glaucoma, diabetic retinopathy, and age-related maculopathy was recorded. Blindness was defined as logMAR visual acuity of 0.99 (Snellen equivalence 20/200 in the better eye) or worse, 'low vision' was defined as Snellen equivalence of 20/63 or worse (logMAR 0.5 or higher), and visual impairment was defined as visual acuity worse than 20/40. Results: The median age was 56 years. Two hundred and eighty four subjects did not attend for eye examination. Of the 922 examined, 128 subjects (13.9%) were 'visually impaired,' 39 (4.2%) had 'low vision,' and 6 (0.7%) were bilaterally blind. The overall prevalence of cataract, open-angle glaucoma, age-related macular degeneration, and diabetic retinopathy were 77%, 1.0%, 8.7%, and 8.8%, respectively. Conclusion: Visual impairment rates amongst Asians seem to be similar to Caucasian populations in the UK. The prevalence of cataract and diabetic retinopathy is higher, while the risk of ARMD and OAG are comparable. In view of the high cataract prevalence, a more detailed assessment of the visual profile and factors limiting healthcare accessibility in this community are needed.

Retained soft contact lens masquerading as a chalazion: A case report
Pankaj Kumar Agarwal, Taha Y Ahmed, Charles J M Diaper
February 2013, 61(2):80-81
DOI:10.4103/0301-4738.107202  PMID:23412528
A misplaced contact lens is a common ocular emergency presenting to the eye casualty. We report a case of lost soft contact lens which migrated in the lid and presented 13 years later with symptomatic eye lid swelling. Authors in the past have reported migration and subsequent retention of lost hard lenses in locations such as the superior fornix and eyelid. To the best of our knowledge, misplaced soft contact lens masquerading as a chalazion has not been reported in the literature. Consideration should be given to the possibility of a retained contact lens in a patient with a history of a lost or misplaced lens, and examination of the ocular surface with double eversion of the upper lid should be performed.

Penetrating orbital injuries from plant material during pond and river diving
Usha R Kim, Kavitha R Sivaraman
February 2013, 61(2):76-77
DOI:10.4103/0301-4738.107199  PMID:23412526
Diving into lakes and ponds is a common activity of rural children. We present two cases of penetrating orbital injuries from plant matter sustained in this manner. Such injuries pose a particular challenge because wooden foreign bodies are often missed during orbital exploration, and current imaging modalities cannot reliably identify retained organic material. When a patient presents with orbital penetration after a high-risk mechanism of injury, such as freshwater diving, the clinician must maintain a very high index of suspicion for retained wooden foreign body.

Khodadad Moradian, Ramin Daneshvar, Ladan Saffarian, Habibollah Esmaeeli, Hanieh Hosseinnezhad
February 2013, 61(2):71-73
DOI:10.4103/0301-4738.107196  PMID:23412524
Purpose: To evaluate the safety and efficacy of viscocanalostomy in the management of medically uncontrollable primary open-angle glaucoma (POAG) in a developing country. Materials and Methods: This is a prospective, non-randomized case series of 14 consecutive eyes with medically uncontrollable POAG, all subjected to viscocanalostomy. The main outcome measure was success rate based on the intraocular pressure (IOP) level achieved post-operatively. The procedure was considered a complete success if IOP was less than 21 mmHg without any anti-glaucoma medication. Qualified success was defined as IOP of less than 21 mmHg with anti-glaucoma medication. All patients had a regular follow-up of at least 12 months. Results: IOP was reduced from a mean baseline value of 27.9 ± 7.3 mmHg (range: 21-40 mmHg) to a mean final value of 16.0 ± 2.7 mmHg (range: 13-22 mmHg), which was statistically highly significant (P < 0.005). The mean number of pre-operative anti-glaucoma medications was 3.0 ± 0.4 (range: 2-4), which was reduced significantly (P < 0.0001) to 0.3 ± 0.6 (range: 0-2) at the last follow-up visit. One year post-operatively, complete success was achieved in 71% and qualified success was observed in 21.4% of patients, summing up to an overall success rate of 92.4%. There were no major complications in any of the patients. Conclusion: Viscocanalostomy could be performed effectively and safely for control of POAG in developing countries.
