The diurnal variation for normal eyes is between 3 and 6 mmHg and the variation may increase in glaucomatous eyes. During the night, intraocular pressure may not decrease [17] despite the slower production of aqueous humour. [18] Glaucoma patients' 24-hour IOP profiles may differ from those of healthy individuals. [19]
Accounts receivable refers to the outstanding balance of accounts receivable at a point in time here whereas average sales per day is the mean sales computed over some period of time. This can be annual as in the formula above, or it can be any period of time considered useful to the company.
For eye pressures, a value of 28 hPa (21 mmHg) above atmospheric pressure 1,010 hPa (760 mmHg) is often used, with higher pressures leading to a greater risk. [2] [26] However, some may have high eye pressure for years and never develop damage. [2] Conversely, optic nerve damage may occur with normal pressure, known as normal-tension glaucoma. [27]
Asset and expense accounts have a normal debit balance, while liability, equity and income accounts have a normal credit balance. [1] Generally a normal balance is shown in statements as a positive number. In the case of a contra account, however, the normal balance convention is reversed and a normal balance is reported either as a negative ...

Individual transactions are posted both to the controlling account and the corresponding subsidiary ledger, and the totals for both are compared when preparing a trial balance to ensure accuracy. For example, "accounts receivable" is the controlling account for the accounts receivable subsidiary ledger. In this subsidiary ledger, each credit ...
Current assets include cash, cash equivalents, short-term investments in companies in the process of being sold, accounts receivable, stock inventory, supplies, and the prepaid liabilities that will be paid within a year. [1] Such assets are expected to be realised in cash or consumed during the normal operating cycle of the business.
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
