Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To compare anatomic and functional results, and to evaluate postoperatively the healing process in 2 different techniques for the closure of the macular holes (MH)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with macular holes classified in stages 3 and 4 will be randomized into 2 groups. . In Group A, patients will undergo peeling with complete removal of the internal limiting membrane (ILM) and in the group B, the inverted ILM peeling technique will be performed. The 20% sulfur hexafluoride (SF6) gas will be used as a tamponade agent in all surgeries, and patients will be instructed to avoid the prone position for 5 days.

OCT images will be performed in the first 5 postoperative days and months 1, 3 and 6.

The primary outcome is anatomic closure of the MH closure in the month 6. The second outcomes are: mean best corrected visual acuity (BCVA) at month 6, mean change in the BCVA at month 6; integrity of the perifoveal external limiting membrane and ellipsoid zone on Optical Coherence Tomography (OCT); MH closure rate over time in days; functional improvement of microperimetry Statistical analysis will be performed with Student t-test and the p-value of ≤ 0.05 is considered significant.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A: Conventional ILM peeling

peeling with complete removal of the internal limiting membrane (ILM)

Group Type ACTIVE_COMPARATOR

Conventional ILM Peeling

Intervention Type PROCEDURE

peeling with complete removal of the internal limiting membrane (ILM)

GroupB: Inverted ILM Peeling

the inverted ILM peeling technique, in which the ILM is left in the edge of the macular hole and the free area is inverted over the macular hole before fluid-air exchange

Group Type ACTIVE_COMPARATOR

Inverted ILM Peeling

Intervention Type PROCEDURE

the inverted ILM peeling technique - the technique of Inverted flap described by Michalewska, in which the ILM is left in the edge of the macular hole and the free area is inverted over the macular hole before fluid-air exchange
