ABSTRACT
We report a case of progressive congenital retinoschis is where the schisis cavity collapsed following argon laser photocoagulation. Despite reports to the contrary, we feel that in the absence of significant vitreous or inner layer traction, photocoagulation applied as light burns in the schisis cavity may be beneficial in collapsing the cavity. Whether or not this collapse of the schisis cavity reduces the risk of rhegmatogenous retinal detachment is unclear.

PURPOSE: To determine chromosomal abnormalities and inheritance pattern in patients with retinoblastoma from a referral hospital in southern India. MATERIALS AND METHODS: Eighty-one retinoblastoma patients from 78 families were included in this study. Peripheral venous blood was taken for chromosomal analysis and pedigree was ascertained for segregation analysis. RESULTS: Male to female ratio was 1.7:1, 55.56% were bilateral retinoblastoma, the mean age of onset was 12.37 months in bilateral and 33.07 months in unilateral cases (p=0.048). Majority (90.12%) had sporadic inheritance and 6.17% had autosomal dominant inheritance. In chromosomal abnormalities, 8.33% had 13q14 deletion, three cases had de novo balanced translocations. CONCLUSION: The age of onset of the disease was much earlier in the bilateral cases compared to unilateral cases. Sporadic inheritance was predominant while only a small percentage of patients had autosomal dominant inheritance. The percentage of patients with 13q14 deletion was higher than reported in the literature and three novel chromosomal translocations were observed. This is one of the largest series of cases reported from India.

A case of bilateral accidental globe penetration during administration of retrobulbar steroid for bilateral optic neuritis is discussed. One eye with bisected macula was managed successfully by vitrectomy, internal gas tamponade, and postoperative laser to the edges of the retinal tear. The fellow eye was blind due to central retinal artery occlusion.

PURPOSE: To evaluate the efficacy of pH-adjusted bupivacaine in conjunction with medial orbital periconal block (periocular anaesthesia). METHODS: Sixty consecutive patients undergoing primary vitreoretinal surgery were enrolled prospectively. RESULTS: Adequate anaesthesia and akinesia with no intraoperative supplementation was achieved in 53 eyes (88.3%). Factors influencing intraoperative supplementation were combined vitrectomy with scleral buckling (p = 0.005) and duration of surgery of more than 2 hours (p = 0.001). No ocular or systemic complication resulted. CONCLUSION: pH-adjusted periocular anaesthesia is safe and effective in patients undergoing primary vitreoretinal surgery.

The management of intraocular tumours has come a long way since the days when enucleation was the only modality of treatment available to the ophthalmologist. Despite the fact that enucleation is still necessary in certain situations, the emphasis is currently on conservative management, thereby saving the eye and some amount of useful vision wherever possible. This review highlights the current trends in the management of adult intraocular tumours with emphasis on newer diagnostic modalities such as computed tomography, magnetic resonance imaging, and fine needle aspiration biopsy. Only those tumours that are most likely to be seen in clinical practice are included.

Fine needle aspiration biopsy (FNAB) was done in 5 patients who reported with atypical clinical presentation of intraocular tumour. The procedure was useful in 4 out of 5 cases and was without complications. With close co-operation between ophthalmologist and pathologist, FNAB is an useful adjunct for accurate diagnosis in selected patients.

Maintenance of pupillary dilatation is necessary for success of scleral buckling procedures. The efficacy of 0.03% flurbiprofen in preventing intraoperative miosis was evaluated by a prospective randomized, double-masked controlled trial of 60 patients. Thirty patients received 0.03% flurbiprofen 6 times at 15 minute intervals 90 minutes preoperatively in addition to the routine dilation regimen. The treated group had a mean pupillary decrease of 1.88 mm and the control group had a decrease of 1.57 mm (p > 0.05). Flurbiprofen did not affect the pupillary size at any step of the surgery. Factors such as age of the patient, lens status, number of cryo applications, duration of surgery, and the size and extent of buckle were assessed. The use of flurbiprofen did not affect the mean pupillary change for any of these groups. Preoperative use of flurbiprofen does not significantly decrease intraoperative miosis during scleral buckling procedures.
