The most common presenting signs of RB in Asian Indian population are leukocoria and proptosis. With appropriate treatment, the survival rate is favorable at 92%.

The Lac-Q questionnaire is a simple and useful tool to evaluate the quality of outcomes of powered endoscopic dacryocystorhinostomy.

Purpose:The purpose was to study the efficacy of interferon alpha 2b (INF α2b) in the treatment of ocular surface squamous neoplasia (OSSN) and analyze its cost-effectiveness in India.Study Design:This was a retrospective study of thirty patients with OSSN treated with topical INF α2b (1 MIU/cc) ± perilesional INF α2b (5 MIU/cc).Results:The tumor involved cornea (n = 9, 30%), conjunctivo-limbal-corneal surface (n = 19, 63%), or bulbar conjunctiva (n = 2, 7%). The mean basal dimension of the tumor was 16 mm. The tumors belonged to Tis (n = 6, 20%) or T3 (n = 24, 80%) based on the American Joint Committee Classification, 7th edition. In the six patients with Tis, three cycles of topical INF α2b were used for immunoprevention. In the remaining 24 patients, INF α2b was advised for immunoreduction, but served as immunotherapy with 100% tumor regression in 22 (92%) cases, and resulted in 95% immunoreduction in 2 (6%) cases. Complete tumor regression by immunotherapy (n = 22) was achieved with a mean number of three topical INF α2b cycles and two perilesional injections. All these 22 patients received three additional topical INF α2b cycles after complete tumor regression. For immunoreduction (n = 2), both patients received six cycles of topical INF α2b which was three perilesional INF α2b injections. The mean total treatment cost per patient with INF α2b was INR 9164 ($US 137). Based on maximum basal diameter of tumor at presentation, the mean total treatment cost per patient with INF α2b was INR 4866 ($US 73) for eyes with microscopic evidence of tumor residue (n = 6), INR 9607 ($US 143) for tumors ≤10 mm (n = 13), and INR 10,985 ($US 164) for tumors >10 mm (n = 11), with two patients needing additional surgical excision for complete tumor control.Conclusion:INF α2b can be used for immunoreduction, immunotherapy, or immunoprevention of OSSN. INF α2b is a cost-effective treatment modality for OSSN at an average total treatment cost of INR 9164 ($US 137) per patient.

High-risk intraocular retinoblastoma is more common in Asian Indians compared with Americans.

In this study, the patients with retinoblastoma with prolonged duration of symptoms (> 6 months) had a three-fold greater risk and those with secondary glaucoma at presentation had a two-fold greater risk of massive choroidal tumor infiltration.
