Membranous type of inflammation of conjunctiva is an uncommon type of conjunctivitis. This condition is associated with the formation of fi­brinous exudates on the surface and into the substance of the epithelium of conjunctiva. It may be caused by a variety of noxious influences, the most common types being due to or­ganisms (like diphtheria, streptococci) or chemical irritants like acids or al­kalies. Rarely, membrane formation on the conjunctiva may be associated with bullous mucocutaneous lesions like erythema multiforme, benign mucous membrane pemphigus. The condition of ligneous conjunctivitis, is very rarely encountered, only 50 cases having been reported till 1965 (DUKE ELDER. [2]

During the last two years at the General Hospital and JIPMER Hos­pital, Pondicherry there were eight patients with membrane formation on the conjunctiva, as shown in [Table - 1].

Since the cause of membranous conjunctivitis other than ligneous conjunctivitis are well known, only the latter condition will be discus­sed.

The condition of ligneous conjunc­tivitis is characterised by the forma­tion of a membrane on the conjunctiva in children, persisting for months and years and later leading to the forma­tion of granuloma of hyaline connec­tive tissue. Because of the woodlike firmness of the resulting granuloma, the term ligneous conjunctivitis was suggested by BOREL [1] . Other names by which this condition has been de­signated are chronic membranous conjunctivitis, recurrent membranous conjunctivitis.

Case No. 1: ­

G - an eight year old boy present­ed with irritation of the left eye of a few weeks duration. Previous his­tory revealed sore eyes at the age of two months which was followed by shrinkage of the right eye.

Examination revealed a phthisis bulbi of the right eye. The left eye showed congestion of fornix and on everting the upper lid, there was a whitish membrane on the tarsal con­junctiva measuring 10 mm horizon­tally and 4 mm vertically [Figure - 1]. The membrane was adherent to the tarsal conjunctiva and removal re­sulted in bleeding. The cornea, and bulbar conjunctiva were normal. His visual acuity was 6/6 and the fundus was normal. Similar lesions were pre­sent in the upper tarsal conjunctiva of the right eye. Examination of nose and throat was normal. The child was suspected to be having diphtheri­tic conjunctivitis and 20,000 units of antidiphtheritic serum was given. Along with local instillation of peni­cillin drops, injections of penicillin were given intramuscularly. Two days later the lesions appeared slight­ly smaller but did not disappear.

The smears examined by direct staining and cultures failed to reveal any organism. General examination (including dermatological examina­tion) showed nothing abnormal. Two months later, when the child was seen again, the lesion had assumed its original dimensions. A small por­tion of the membrane was removed and subjected to bacteriological and histological examinations. No orga­nisms could be cultured and histology revealed a fibrinous exudation with lymphocytes and polymorphs [Figure - 2].

All this time the child had minimal eye symptoms. Twelve months later when seen again, in the middle of the membrane a polypoidal mass could be seen [Figure - 3]. This was ex­cised and when subjected for histo­logical examination showed hyalinis­ed areas in the submucous region with scanty cellular reaction [Figure - 4].

During all this time the vision in this eye has stayed normal.

Case No. 2:­

M- a three year old female child was brought to the General Hospital with the complaints of redness, irritation and mild discharge. Exam­ination revealed a well built but poorly nourished child. Ocular exam­ination revealed a congested superior fornix of the right eye. On everting the lid a membrane was seen on the palpebral conjunctiva 5 mm X3 mm, firmly adherent to the underlying tarsal plate. Attempts at separation resulted in bleeding. A part of the membrane was subjected to smear and cultural examination. 20,000 units of antidiphtheritic serum was given intramuscularly along with penicillin drops. There was no re­gression of the membrane with the treatment. No organisms could be demonstrated in the smear and cul­tures. The child was attending the hospital regularly for nearly ten months and during this time there was neither any change in the size nor appearance of the lesion. The patient has failed to return for fur­ther follow up.


  Discussion Top


This condition of ligneous conjunc­tivitis has a predilection for children (2-6 years) and is more common in females (DUKE ELDER [2] ).

The condition is usually bilateral affecting often both upper lids, but sometimes all four lids. It frequent­ly has an acute onset and may be associated with nasopharyngitis.

The membrane is chronic and re­curs following attempts at surgical removal. Eventually the membrane is replaced by a granuloma forma­tion.

The pathogenesis of the condition is uncertain.

Bacteriological examination is ne­gative, occasionally secondary bac­terial invaders may be present. VER­HOEFF [5] postulated that the primary infectious agent in ligneous conjunc­tivitis may be a virus.

GOLDMAN AND HOF [3] consider that the disease may be familial. Their patient belonged to a family which in two generations had five cases. They therefore, concluded that a familial hereditary lowering of resistance played an important role in the disease. WINTER AND MICHLER [6] reported the cases of two brothers affected with the disease at an interval of about one year. It was noted by these authors that a mem­brane could be induced to form in a previously uninvolved area by trau­matizing the conjunctiva with forceps. Traumatizing the conjunctiva with carbondioxide snow (dry ice) also in­duces the formation of a membrane. It is possible that ligneous conjuncti­vitis depends not only upon heredi­tary susceptibility to the original in­fection, but also upon an hereditary peculiarity of the palpebral tissue in its response to injury.

The treatment in the absence of a aetiological factors is unsatisfactory. In the acute phase, use of antibiotics may protect the cornea by preventing secondary infection. But the anti­biotics and corticosteroids have not been found to decrease the severity or shorten the course of the disease.

Surgical treatment of granulomas is not advisable, due to recurrences. PAUFIQUE AND MOREAU [4] by re­peatedly treating the denuded area by beta rays, prevented recurrences of the granulomas. As these cases are otherwise symptom free, and the dis­ease does not affect the vision, it is advisable to leave them alone. In VERHOEF'S [5] case the granulomas persisted for 36 years without affect­ing the vision.

The essential features of ligneus conjunctivitis are summarized below.

  1. Predilection for children:
  2. Chronic course. Yellowish white membrane on the tarsal conjunc­tiva [Figure - 1] leading to a palpe­bral granuloma- [Figure - 3].
  3. Histological examination: essen­tially fibrinous exudates [Figure - 2] with development of hyaliniza­tion of submucous region [Figure - 4] in the granuloma stage.
  4. Rapid reformation of membrane on the conjunctiva following at­tempts at removal.
  5. Hereditary peculiarity of palpe­bral tissue to trauma (WIN­TERS).
  6. Treatment is unsatisfactory. It may be left alone.
  7. Vision is usually not affected (except when the initiation of the disease is as an acute process (Case No. 1).



  Summary Top


One histologically proven case of Ligneous conjunctivitis starting as an acute process is presented. A second case where the membrane formation on the conjunctiva is persisting for nearly ten months is also showing some of the features of this type of conjunctivitis. However, no granu­loma could be seen during the period of her follow up. The condition has two distinct clinical phases - mem­branous or pseudomembranous stage -followed by a chronic course lead­ing to the palpebral granuloma stage. The first case showed both the stages while the second case showed only the membranous stage lasting ten months, - the period of follow up.
