Prof Amitava completed his graduation (1984) and masters in ophthalmology (1992) from the Armed Forces Medical College, Pune. In between, he did a 5-year stint in the Army Medical Corps. Subsequently, he served as a consultant in the Gandhi Eye Hospital for 3 years, and looked after their Community Outreach program; also being exposed to a month long fund raising pan-Canadian Lecture tour. He has been teaching since 1995, with numerous publications in peer-reviewed journals, concentrating essentially on strabismus. Two novel approaches have included true muscle transplantation for large angle strabismus, and re-attaching rectus muscles with cyanoacrylate and demonstrating the feasibility of a suture-less option. His other interests involve medical statistics and medical education technology. Citation indices All Since 2012 Citations 97 54 h-index 6 4 i10-index 3 1

  1. Single-snip paralimbal incision: A quick approach to rectus muscles: OJO 2021

    Saxena J, Akhtar N, Gupta Y, Amitava AK, Kauser F, Ahmed S, Raza SA, Masood A. Single-snip paralimbal incision: A quick approach to rectus muscles. Oman J Ophthalmol. 2021 Feb 27;14(1):3-7. doi: 10.4103/ojo.OJO_188_2020. PMID: 34084027; PMCID: PMC8095299.


    Less invasive and quicker surgeries have become common. We compared two conjunctival incisional approaches in strabismus, namely Follow standard paralimbal approach for (SPLA) and single-snip paralimbal (SSPLA).


    Forty-four patients with horizontal strabismus qualifying for uniocular recession–resection surgeries were randomized to SPLA and SSPLA. SSPLA involved a single v-shaped incision, with the apex of the V near the limbus, and the limbs facing away: by pinching up the conjunctiva with a forceps and delivering the single snip with a spring scissors. We compared the postoperative grades of redness, congestion, chemosis, foreign body sensation, and drop intolerance at day 1, 2 weeks, and 6–8 weeks; scar visibility, as yes or no, at 6–8 weeks; success rates, considered to be within 10 prism diopters of orthophoria, at 6–8 weeks; and operation duration in minutes.


    Statistical analysis was done using Mann–Whitney U-test, for inflammatory grades, Chi-square for proportions, and t-test for parametric measures. Statistical significance was set at P < 0.05.


    On postoperative day 1, congestion (P = 0.02), foreign-body sensation (P = 0.04), and total inflammatory score (P = 0.003) were statistically significantly favoring the SSPLA group. While at 2 weeks, only congestion (P = 0.02) was found to be significantly less in the SSPLA group. There were no significant differences in the proportions of scar visibility (5/22 in the SPLA vs. 3/22 in the SSPLA) and success rate: 20/22 vs. 18/22. The SSPLA was quicker on an average by 6 min (P < 0.001, 95% confidence interval: 3.2–8.7).


    Compared to the SPLA, the SSPLA is quicker and results in lesser inflammation in the immediate postoperative period.
