Recurrent ligneous conjunctivitis after cataract surgery in a 67-year-old male patient: a case report

Ligneous conjunctivitis is a rare form of chronic pseudomembranous conjunctivitis which usually starts during infancy. We report on an unsual case of recurrent ligneous conjunctivitis after cataract surgery in a 67-year-old male patient. The equipment used for the slit-lamp images was a Haag Streit slit lamp BX900 Sn 00,406 with 16 × magnifications. The used batch number of the camera was sn00406 and the software was from the company CCS Pawlowski Merge Eye. There were no filters used. The images were saved with a resolution of 300 DPI. Neither downstream nor averaging was used to enhance the resolution of the image in the case presentation section or the figure legend. The equipment used for the cross-sectional histologic images was a Zeiss Axioskop 40 microscope with an objective lens Zeiss A-Plan × 20/0.45 (Zoom 6.3 × TV 2/3″″C). The used camera was AxioCam MRc5 and the software was ZEN 3.2. The cross-sectional histologic images were saved with a resolution of 2584 × 1936 Pixels. Neither downstream nor averaging was used to enhance the resolution of the image in the case presentation section or the figure legend. This is a rare case report of ligneous conjunctivitis in a 67-year-old male patient who presented a recurrent conjunctival granuloma after five excisions following cataract surgery in his left eye. We performed a tumor excision with free conjunctival autograft. The histology showed a fibrin crust including macrophages, granulocytes, lymphocytes, and reactively altered squamous cell nests. These findings were consistent with a ″pseudomembrane in conjunctivitis lignosa″. We administered a topical combination of plasminactivator, heparin, cortisone and cyclosporine. This treatment with the combination of plasminactivator, heparin, cortisone and cyclosporine has proven to be effective in preventing the recurrence of ligneous conjunctivitis.
