Clinical and pathological correlation of cotton wool spots in secondary angle closure glaucoma

Although not commonly associated with glaucoma, CWS can present in the setting of acute elevations of IOP and may be associated with loss of nerve fiber layer. This loss of nerve fiber layer can confound the ability to judge glaucoma progression based on nerve fiber layer thickness via optical coherence tomography and changes in disc contours. Patient care may benefit from care provider's awareness of this possible phenomenon in the setting of angle closure.
