Anterior chamber depth and lens thickness in primary angle-closure glaucoma : A case-control study
Sandeep Saxena, PK Agrawal, VB Pratap, Rajiv Nath
April-June 1993, 41(2):71-73
Anterior chamber depth and lens thickness have been considered as important biometric determinants in primary angle-closure glaucoma (PACG). In a tertiary care centre-based case-control study, 70 patients and equal number of controls were investigated to analyse the strength of association and predictability of anterior chamber depth (ACD) and lens thickness (LT) in the disease. Mean (+/- S.D.) ACD and LT in the cases and the controls were found to be 2.28 +/- 0.19, 2.87 +/- 0.10; 4.57 +/- 0.34 and 4.13 +/- 0.19 mm respectively. Two sample t test demonstrated statistically significant difference in the ACD and LT between the cases and the controls (Difference being -0.59, 0.44; 95% confidence interval of the difference: -0.64, -0.53 and 0.34, 0.53 respectively, P < 0.01). Logistic regression analysis demonstrated statistically significant protective effect of ACD over PACG (P < 0.01). The odds ratio corresponding to an increase of 0.01 mm in ACD and LT were computed as 0.83 and 1.11 respectively

Current concepts in the diagnosis and management of developmental glaucomas
Anil K Mandal
April-June 1993, 41(2):51-70
Developmental glaucoma is a global problem and has a broad range of ocular manifestations and is sometimes associated with systemic disorders and syndromes. It poses a major diagnostic and management problem to the ophthalmologists. A proper diagnostic evaluation under general anesthesia is advisable for all children who do not cooperate for an office examination. Surgery remains the principal therapeutic modality in the management of developmental glaucoma and medical therapy is limited to a supplemental role while the child is being prepared for surgery. Conventional angle incision surgery (goniotomy and trabeculotomy ab externo) is uniquely valuable in the management of primary developmental glaucoma, while combined trabeculotomy cum trabeculectomy offers the best hope of success in advanced cases. In recent years, artificial drainage devices such as the Molteno implant seem to be promising for safe and effective pressure control in children with refractory developmental glaucoma. Visual rehabilitation involves correction of refractive errors, removal of opacities in media (i.e. cataract or corneal scarring) and aggressive amblyopia therapy. Early diagnosis, prompt institution of therapy combined with commitment from the family for postoperative follow-up care are critical for the restoration of good visual function.

Intraoperative Mytomycin C in complicated glaucomas
Gurdeep Singh, Jagmeet Kaur, Ajay Dogra
April-June 1993, 41(2):78-80
Filtering surgery has been found to be less successful in certain types of glaucoma. These include young patients, those with pigmentary glaucoma, secondary glaucoma, angle recession glaucoma, aphakic or pseudophakic glaucoma, and patients requiring reoperation. This study describes the authors' attempt to evaluate the effectiveness of conventional trabeculectomy with intraoperative application of mitomycin C in such patients. Ten eyes of 8 patients were evaluated in this study. Of these cases 4 eyes (2 bilateral cases) were from the primary juvenile open angle group; 2 eyes each had pseudophakic glaucoma and previous anti-glaucoma surgery which had failed; one eye had aphakic glaucoma and the last suffered from angle recession glaucoma. The intraocular pressure was successfully controlled in all the ten eyes. The preoperative IOP ranged from 28 to 50 mm Hg and the postoperative IOP ranged from 7 to 16 mm Hg. The postoperative complications were minimal

The role of 5-fluorouracil in complicated glaucomas
AM Khan, FA Jilani, S Das
April-June 1993, 41(2):74-77
The long-term efficacy of trabeculectomy in controlling intraocular pressure (IOP) has been found unsatisfactory in various complicated and refractory glaucomas. The most common cause for failure is excessive scarring at the filtering site. Several wound modulating agents which reduce scarring have been tested. In this study, 5-Fluorouracil (5-FU), a halogenated pyrimidine analogue and a potent anti-mitotic agent, was applied for seven days after trabeculectomy in eighteen complicated and unsuccessful filtering glaucomas, at a daily dosage of 5 mg in the form of 0.5 ml subconjunctival injections. The common postoperative complications encountered were corneal epithelial erosion (38%), wound leakage (16%), subconjunctival haemorrhage (32%) and hyphaema (10%), all during the first 7 to 10 days. Monitoring at regular intervals up to six months showed adequate control of IOP (less than 22mm Hg.) in 88% of the cases. Cases of aphakic glaucoma and neovascular glaucoma showed poor response. Use of 5-FU as an adjuvant to filtering surgery in various complicated glaucomas improves the long-term results

Releasable suture technique for trabeculectomy
Pushpa Jacob, Ravi Thomas, Anuradha Mahajan, Annie Mathai, Stephen C Gieser, Renu Raju
April-June 1993, 41(2):81-82
We studied the effect of the releasable suture technique on immediate postoperative intraocular pressure (IOP). Nine eyes of nine patients with glaucoma had trabeculectomy with a releasable suture. In the six eyes that did not receive antimitotics, the suture was released by the fifth postoperative day; in the others suture release was delayed up to the fourteenth day. Of the nine patients, one had an acceptable postoperative IOP and did not need suture release; in another the suture broke and could not be released. In the remaining seven patients, the difference between the pre-release and post-release IOP was statistically significant (p < 0.001). The complications of this technique include failed suture release, subconjunctival hematoma and a distinctive "windshield wiper" keratopathy.
