Summary

Retina Gelfilm, an absorbable gelatin implant, was used in 375 retinal detachment surgeries. This implant provided temporary elevation, with absorption times varying from 2 to 24 months.

Background:

Retinal detachment is a serious condition requiring surgical intervention.
Scleral buckling is a common surgical procedure for retinal detachment repair.
The use of temporary implants can aid in achieving buckle elevation and posterior support.

Purpose of the Study:

To evaluate the efficacy and absorption characteristics of an absorbable gelatin implant (Retina Gelfilm) in scleral buckling procedures.
To assess the implant's performance when used alone or beneath a silicone rubber implant.

Main Methods:

A retrospective analysis of 375 scleral buckling procedures utilizing Retina Gelfilm.
Procedures included 192 trapdoor/scleral pouch techniques and 183 cases with gelatin beneath silicone rubber implants.
Two implant thicknesses (0.5 mm and 0.75 mm) were employed.

Main Results:

Absorption times ranged from 2 to 24 months, influenced by implant thickness and placement (alone or under silicone).
The gelatin implant successfully produced temporary elevation or posterior extension of the buckle in selected patients.
No specific complications related to the gelatin implant were mentioned.

Conclusions:

Absorbable gelatin implants are effective for temporary buckle modification in retinal detachment surgery.
Retina Gelfilm serves as a viable option for achieving desired buckle effects, either independently or in conjunction with silicone implants.
The implant's absorption profile allows for controlled, temporary structural support during retinal reattachment.
