The author describes the phenomenon of convergent squint and ptosis of the upper eyelid caused by relasping herpetic keratitis have not been previously reported, although this possibility should be considered. This observation represents a contribution to the better understanding of herpetic eye disease in general as well as the eventual recognition of the toxic effect of the HSH virus on man in vivo. According to the author these ocular disturbances are provoked by the toxic effect of the human herpes simplex virus and are connected to its neurotropism.

Restrictions have been found to be a common cause of incomitant strabismus and limitation of ocular rotations. Different types of restrictions have been described and the technique of forced duction testing reviewed. Causes of restriction include endocrine eye disease, orbital floor and medical wall fracture, Brown's syndrome, tight lateral rectus syndrome, congenital tight muscles, scarring, muscle contracture, and orbital celluitis or tumors. The importance of recognizing restrictions in the management of these problems has been emphasized.

A behavioral method of screening binocular infant vision called forced choice preferential looking (FPL) has been developed. Clinical trials of the FPL test for young infants are reported here. The test aids nonspecialized personnel in early identification of bilateral ocular abnormalities and anomalies of binocular cooperation (strabismus). It is not possible to screen for monocular eye disease or amblyopia with this test. Modifications of the FPL test may offer new ways of assessing other aspects of visual function early in life.

One hundred twenty-eight patients (most less than 13 years old) with various types of cerebral palsy were examined to assess visual acuity, refractive state, oculomotor functions, sensory fusion, and ocular health. Special procedures for examining these patients are described. Vision or ocular defects were found to be present in 86% of these cerebral palsy patients. Significant refractive errors and strabismus were the most common defects, being present in 50% or more of the patients. Ocular disease was relatively uncommon.

Strabismus presenting after cataract surgery is etiologically related to a heterogenous group of disorders. Clinical data from 63 patients so affected revealed four broad etiologic categories: 1) pre-existing disorders that preceded the cataract surgery, but were rendered asymptomatic by the occluding cataract (e.g., thyroid eye disease, cranial nerve palsy, myasthenia); 2) disorders precipitated by prolonged occlusion by a cataract (e.g., sensory deviations, decompensation of heterophorias, and central disruption of binocular vision); 3) disorders resulting from surgical trauma to extraocular muscles and orbital soft tissues. Traumatic injury to the inferior rectus muscle secondary to retrobulbar anesthesia injection, a specific subset, is postulated to result from a Volkmann's type ischemic contracture, a well-known osseofascial compartment syndrome occurring in peripheral skeletal muscles. 4) Disorders related to resulting aphakia/pseudophakia and associated optical aberrations (e.g.; anisophoria, ocular dominance reversal, and color/brightness disparity). The diagnostic and therapeutic implications of these findings are discussed.

Strabismus presenting after cataract surgery has been attributed to a variety of disorders, some of which are unrelated to the surgery. When thorough ophthalmologic and neurologic examinations fail to elucidate a definitive etiology, the motility disturbance is often ascribed to operative trauma to the orbital soft tissues. In a series of 58 patients with strabismus presenting after cataract surgery, eight (14%) were found to have previously unsuspected thyroid eye disease. Three of the eight patients had past histories of systemic dysthyroidism, but none reported diplopia prior to cataract extraction. Three of the remaining five patients showed normal thyroid function tests. Absence of diplopia prior to cataract extraction in these patients may be due to: 1) poor vision precluding diplopia until surgical restoration of sight; 2) intraoperative aggravation of the inflammatory process in otherwise subclinical thyroid eye disease; or 3) onset of clinical thyroid eye disease that was temporally associated with cataract surgery by chance. Thyroid eye disease should be included in the differential diagnosis of all patients presenting with binocular diplopia following cataract surgery. Suitable neuroimaging studies may be needed to confirm the diagnosis.

In 1985-86 an ophthalmologist screened 221 patients, ranging in age from six to 81, at Naerlandheimen central institution for mentally handicapped. The screening showed an alarming incidence of eye disease in this group, regardless of the etiology of the mental handicap or the patient's age. Only 44 patients had completely normal eye status without errors of refraction. 40 patients had errors of refraction only and eight had presbyopia only, but otherwise normal findings. 129 had one or more eye anomalies or diseases. There was a large incidence of cataract (52 cases), keratoconus (21 cases), strabismus (59 cases) and conjunctivitis or blepharitis (17 cases). The result emphasizes the importance of close and frequent examination of the status of the eyes of mentally retarded people throughout their lifespan.

A patient with longstanding dysthyroid eye disease developed a broad adhesion between the globe and the upper eyelid following simultaneous surgery to recess the levator palpebrae superioris and lateral rectus muscles. This unusual complication may have developed as a consequence of failure to suture the conjuctiva of the upper fornix to the tarsus and also due to the prolonged static contact between the resulting adjacent raw areas due to postoperative eyelid traction and pressure dressings. Periods of such contact may have been further prolonged by the action of diazepam, which reduces the peak velocity of saccadic eye movements and suppresses rapid eye movement of sleep. Eyelid surgery should be performed as a separate procedure, under local anesthetic after healing of areas bare of conjunctiva from strabismus surgery utilizing the adjustable suture technique.

Anterior segment circulation was assessed in 35 adults one day after squint surgery by clinical observation and low-dose fluorescein iris angiography. Seventeen patients had primary vertical rectus muscle surgery and all showed angiographic evidence of ischaemia. No ischaemia was found in the 15 patients who had secondary vertical rectus muscle surgery, or any horizontal rectus muscle surgery. The staged group had intermediate findings between the above two. Age, dysthyroid eye disease and type of conjunctival incision did not correlate with fluorescein iris angiographic sector-filling delay on the first post-operative day. The time taken for the sector with delay to fill becomes less during the first two post-operative weeks. Redistribution of iris filling persists, however. This data suggest that the safe interval before further muscle surgery can be done is shorter than has previously been assumed. Since the anterior ciliary arteries do not reform into canals the probable mechanism of redistribution of blood flow is from the long posterior ciliary arteries and increased capacity of the collateral circulation.

BTX injection has been used for 11 years by 292 ophthalmologists in 8,854 patients aged three months to 90 years in a variety of eye muscle and eyelid disorders. No systemic toxic reaction has occurred, local complications are few, and visual loss has not occurred in any case. In blepharospasm and hemifacial spasm BTX appears to fill an important need, since no other drug is reliably effective and since surgical interventions have substantial side effects. Strabismus cases with active uveitis, hypotony, previous detachment surgery, active thyroid eye disease, and recent paralytic strabismus are often poor candidates for surgical intervention. Some patients in each of these categories were treated effectively and safely by BTX injection. Surgery is clearly the preferred treatment modality in large angle deviations, in chronic paralytic strabismus, in cases where diplopia for a month or two from injection would incapacitate the patient, in nystagmus, in oblique muscle disorders and A-V patterns, where muscles have been misplaced and where restrictions to alignment have been created by disease or prior surgery. Side by side comparisons of surgery and injection in congenital esotropia and in concomitant strabismus of 50 PD or less should result in further clarification of treatment choices as to effectiveness, side effects and cost. BTX is presently available only to clinical investigators using the drug under research protocols.
